' IMPROVEMENT IN PAPER-COLLAR MACHINES.

' Specification forming part of Letters Patent No. 5 l ,233', datedNovember i8, 1865.

To all whom it may concern:

Beit known that I, GEORGE K. SNOW, of Watertown,`in the county ofMiddlesex and State of Massachusetts, have made a new and usefulinvention having referenceto'cutting or stamping shirt-collars froma'strip of paper or other material 5 and I do hereby declare the same tobe fully described .in the following specification and represented'inthe accomfemale end and button-hole-die plate. Fig. 7

is a top View, and Fig.8a longitudinal section, of the centralbutton-hole-die plate.

`This machine is intended to stamp out neckcollars from a continuousroll or strip of paper of a Width corresponding to that of a collar tobe made from it. Fig. 9 exhibitsthe arrangement of such collars in thestrip, or the cutsV made in such strip'iu order to reduce it tocollars-th at is to say, the short pieces e, being cut from the strip atequal or proper distances apart, leave collars A A. Each of these co1-lars has a central button-hole, c, and two'end button-holes, d d,stamped through it by the machine. With 'the exception of the smallpieces necessary to the formation of the button-holes, parts such as aremarked ein Fig. 9 are all that it is necessary to remove from the stripin orderto convertitinto collars. In this way of forming the collarsfrom a strip it will be observed that the end of each collar extends bythat of the other, and goes close, or nearly close, up to the upperportion of the Vsaid-other collar. This peculiar arrangement vof thecollars or their ends I claim to be new and of my invention,as well asthe machine forfcutting or-stamping such collars in such manner from astrip.

-In the drawings,A denotes the bed-plate of the machine, which 'isdovetailed into the cutv ter-carriageB, or so applied to it'as to enable the die-plate C. Suitable openings,h t', are formed in the carriageB and the bed-plate A, in

order to lallow the waste separated from the striplby the dies to bedischarged from the plate C.

Y The opening 'i' between the two platesj'gis the female die, by whichthe ends of the collars are formed through the action of a correspondingmale die, 7c, projecting from the bottoni of a plunger, D. (See Fig. 2.)The said plunger plays vertically within a box or frame, E, (fastened tothe carriage B and on the top surface of the die-plate C,) and has across head or bar, Z, bolted across its top and resting on .springs m m,which, in turn, rest on two ears or projections, n n, extended from theends of the box E. `(Spee Fig. 3.) The purpose of the springs on ,in isto eli'ect the elevation of the plunger I) and the Withdrawal of themale die It from the female die t" at the proper periods.

There are two female button-hole dies, o o', formed through `the platef, and there `are also two other female button-hole dies, o 0, formed inthe plate g, they being arranged as shown in Fig. 5. Corresponding maledies should be projected from the bottom of the plunger D, so as toenter and operate with the female dies o o o o in a manner analogous tothat in' which the male die k operates with the female die t.Furthermore, there is applied to the car'- riage B adjustablebutton-hole dies for cutting or stamping from the strip, the middlebuttonhole. dierepresented at c in Fig. 9. The fe male dies of theselastmentioned button-hole dies are shown pin Fig. 7 as made inandthrough a rectangular plate, F, which is arranged on the upper surfaceof the carriage B, and so as to be capable of being slid thereon betweentwo parallel guides, q q, arranged on' the said carriage in manner asrepresented in Fig. l, 2 and 4.'

Corresponding male dies projecting from the plun gers r r, extendingdownward from a crosshead, s, operate with the said female dies p p,one-ot' such male dies being shown at t in Fig. 2. f i

The twoplungers r r play within a standard, u, which projects upwardfrom the plate y F, and has a long screw, G, screwed through 'y it, andso connected with the box E that-on revolving the screw the distance ofthe dieplate F from the die-plate G may be either increased ordii'ninished, as circumstances may require.

Lassagesiv l1n for discharge of the Waste from the dies j; p are madethrough the carriage Ii andthe bed-plate A.

The bar s rests on springs fr, which, in turn, are supported onv ears yy, the same being as shown in liig. 4, the said springs being forelevatingl the dies 1 out of the die-plate F after each descent ot' suchdies.

`Ih con neetion with the mechanism described, I malte use of auadjustable gageplate, H, carrying two projections, s z, which arearranged. on and so as to extend from it, as shown in Figs. 1,2, and 3.This gage-plate slides rectiiinearly on the carriage l5, and is providedwith a clamp-screw, a', by which it can be iixed in position on thecarriage and with reference to the end dies. A straight rib,1,',p1oiecting downward from the plate H, euters a groove, c', made inthe carriage, and at right :ingles with the outer edge. of the platef.The clamp-screw a passes through a groove, d', formed in the plate II,and screws into the carriage.

lt is on one o." the proicctions or guards c that the middlebntton-holeofeach collar, prior to the separation of such collar fromthe strip,

. is placed in order to determine the correct position ofA the lstripfor the end dies to operate in order to out the said collar therefrom.As the middle button-holes of each two next adpaper are not at the sameedge of the strip,

but are situated at opposite edges ,of it, in4

manner. as shown in Fig. Si, it becomes necessary that theprojections z.1: should be used alternately dnring`the process of forming the collarsby the machine.

In going through the machine the strip of paper passes underneath thestandard a and the box E and rests on the dic-plates C and Ii, and is tobe fed along with an intermittent motion. Ireviousto each descent of themale dies the carriage I3 is to be moved laterally, so as to transferthe paper from lone side ot' the middle line ot' the carriage to theopposite side thereot.

Ihe mechanisms for so moving the carriage,

'and for feeding the strip of paper along, and

dies; also, that the two sets of each kind of thc dies are arranged onopposite sides ot' the middle line of the carriage B.

What, therefore, I claim as my invention in the said machine isi 1,. Theabove-described arrangement and combination ot' endend button-hole dies,irrespective of the middle button-hole dies.

2. The above-,described arrangement and combination of end andbutton-hole dies, in-

clusive ot' the middle button-hole dies.

'3. In combination with the end dies and the middle button-hole dies,arranged as specified, a mechanism for adjusting the distance of thesaid middle button-hole dies from the end forming-dies. i f

4. In combination with the end cutting-dies and the middle button-holedies, arranged as described, the gages z e, whether stationary on'thecarriage B or adjustable thereon, a's specified.

v5. The end forming-dies, substantially as described, for shaping thecontiguous ends ot' two collars at one operation.

6 The formation of collarsin a continuous strip in the' manner, or' withtheir ends to overlap one another, as hcreinbefore described, and asrepresented in Fig. t).

7. The formation of collars from a continu ous strip of paper, asdescribed, by means of end forming-dies arranged as specified, and byalternately changing the strip from one `side to the other of the middleline ot' the dies, as specified.
